Passively, via diffusion.

Glucose is transported into cells through facilitated diffusion or active transport, depending on the concentration gradient. Amino acids are transported into cells through specific transporters in the cell membrane.
The endoplasmic reticulum transports newly made proteins within the cell. Proteins are synthesized on ribosomes attached to the rough endoplasmic reticulum, and then they are folded and transported to their final destination within or outside the cell.
Amino acids are the building blocks of proteins, including transmembrane proteins. The specific sequence of amino acids in a transmembrane protein determines its structure and function. Some amino acids have hydrophobic properties, which help anchor the protein within the cell membrane. Other amino acids form hydrogen bonds and other interactions that stabilize the protein's structure and allow it to perform its specific function, such as transporting molecules across the cell membrane.
Amino acids tend to diffuse from a blood capillary to the adjacent cell because of the concentration gradient that exists between the two compartments. This process is facilitated by specific transport proteins on the cell membrane that allow the amino acids to move across the membrane. Additionally, the polarity and charge of amino acids play a role in their movement across the cell membrane. Overall, the diffusion of amino acids is a crucial mechanism for nutrient uptake and cellular function.
All cells synthesize (build) proteins from amino acids. The information that the cell needs in order to arrange the amino acids in the right sequence is stored in DNA.
Ribosomes, cell structure that uses genetic instructions transported in Ribonucleic acid (RNA) to link a specific sequence of amino acids into chains to form protiens. Ribosomes are dispersed in the cytoplasm (the cell contents outside the nucleus) of all prokaryotic cells.
If a cell did not have amino acids or the ability to produce them this would mean that cell did not have the plasma membrane and the membranes that surround a cellâ??s organelles. In this situation a cell would not have the ability to fix damage it sustained or be able to reproduce.
The lower the amount of ATP, especially if there is none present, the concentration of amino acids outside of the cell will be much greater than on the inside, because amino acids need to be aided by a sodium ion. Sodium is pumped outside of the cell (where the amino acids are) by the sodium-potassium pump which needs ATP to function; therefore, if there is no ATP, the pump will not operate, there will be no sodium ions on the outside to aid amino acids into the cell.
Metabolism
By having more codons to code a particular amino acids, it makes it easier to produce in the cell and need to be supplemented from food(essential amino acids are normally not synthesized in our cell).
a very hard question
